dudeski, I'll split up my answers.
1. I don't believe OEMs should be allowed to add proprietary software to
their computers. It takes away freedom from the computer users. Free
software is OK for them to add on.
2. The thing I have against BSD-style and MIT-style licenses is that compared
to copyleft licenses is that they allow developers to turn their software
into proprietary software. Instead of glibc I'll give another example, let's
say Linux was relicensed under a BSD-style license. This would make it
significantly easier for developers of proprietary drivers to create them.
Meaning that there would be no more glue. BSD-style licenses do not
discourage the creation of proprietary software.
